The Rolex Awards: a cheap technique for food preservation, M. B. Abba
Nigerian teacher Mohammed Bah Abba was motivated by his concern for the rural poor and by his interest in indigenous African technology to seek a practical, local solution to these problems. His extremely simple and inexpensive earthenware "pot-in-pot" cooling device, based on a principle of physics already known in ancient Egypt, is revolutionising lives in this semi-desert area.
